To @ZZ ifi/wm it 71mg/ con/cern:

Be it known that I, EDWARD D. HABE, a citizen ot the United States,residing at Erie, in the county of Erie and State of Pennsyl vania, haveinvented certain new and useitul Tmprovements in Nut Locks; and I dohereby declare the followingto be a full, clear, and exact descriptionof the invention7 such as will enable others skilled in the art to whichit appertains to make and use the same. reference being` had to theaccompanying drawing-s, and to the letters ot reference marked thereon,forming part of this specification.

This invention rel ates to nut-locks, the object thereof being toprovide mechanism which can be screwed down upon the threads ot the boltagainst the nut to prevent the nut trom becoming` unscrewed.

The features ot my invention are herein iter particularly described andpointed out and are illustrated in the accompanying drawings in whichFigure l, is a view in elevation of a bolt, with a portion thereofbroken away, showing the nut and nut-locking' mechanism thereof intransverse vertical section.

Figure 2, is a transverse section on the line 2-2 in Fig. l.

Figure 3, is a transverse vertical section of a part ot my locking`mechanism.

Figure 'i, is a plan view ot another part thereof.

ln these drawings A indicates a. bolt having threads u on a portionthereo'l'. In preparingthe bolt 't'or my inun'oved nut-lochr` ingmechanism lY provide a` longitudinal slot or groove a which is cuttransversely of the threads a.. B indicates a nut screwed upon thethreads u. ot the bolt` C indicates an internally screw threaded ringadapted to he placed upon the part of the bolt A which projects throughthe nut B. This ring (lV (see Figs. 2 and 3) is also provided withradial holes C through the wall thereof. Surrounding the ring C isanother ring D which is provided with a spring pressed bolt D.

Specification of Letters Patent.

. spring` Patented Jan. 17, 1922. 1921. serial No. 480,737.

This bolt D is slidably mounted in a short sleeve (l, which is radiallysecured in the ring D. and within the sleeve CZ is placed a spring dadapted to maintain the bolt D in the position thereof. shown in thedrawings. The sleeve (Z is also provided with a slot Z2 through which aring` D2 is placed; said ring also passing through transverse hole inthe bolt D; said ring` D2 being` for the purpose ot pulling` the bolt Dbackward out ot a hole C in the internally screw threaded ring C.

Tn operation the nut B is placed upon the bolt A and screwed down uponthe threads a ot the bolt A. and the ring; D is then placed around thering C, the spring` pressed bolt D being drawn backward so to allow thering` D to slip over the ring C.

The ring D is turned backward on the ring` (l until the spring' pressedbolt D enters one ot the radial lioies C in the ring` C, and then byturning' the ring D. the bolt D moves the ring C in unison therewithuntil the spring pressed holt. D snaps into the lonoitudinal slot a.rllhis operation of the pressed bolt D. and rings C and D can berepeated until the ring C is screwed firmly down upon the nut B,leavingr the spring` pressed holt D projecting4 into the slot a. in thebolt A.

Having thus shown and described my invention so a. to enable others toutilize the same what l claim as new and desire to secure hy LettersPatent is ln a device of the class describe-d, a screwtlneaded holthaving' u loiuritudiual slot in the periphery thereof. a nut securedupon said bolt. au internally scre\\'thrcaded ringf having radial hotestherein engaging the bolt threads. aringv rotatably mounted on saidscrew-threaded ring. a spring-pressed lockingbolt radialh,y mounted insaid ring and adapted to extend inwardly through a hole in saidscrew-ring and into the longitudinal slot in said bolt. i

In testimony whereof I aitix my signature.
